If you’ve ever fallen down the TXT rabbit hole, you’ve probably asked yourself the same question at some point:
“How are five people this different, yet somehow this perfectly matched?”
Yeonjun’s commanding presence that fills a room without demanding it. Soobin’s warm, steady anchor energy. Beomgyu’s surprising emotional depth behind all that chaos. Taehyun’s sharp, unshakeable conviction. Huening Kai’s wide, free-spirited vitality that glues everything together. Each of them is unmistakably their own person — and yet on stage, they move like one.
Korean saju (사주, four pillars astrology) offers a fascinating lens for reading exactly this kind of dynamic. And when you line up all five members’ birth charts, the chemistry starts to look a lot less like coincidence.
What Is Saju? A Quick Primer
Saju — sometimes called Korean astrology or four pillars astrology — is a system rooted in East Asian philosophy that maps a person’s innate character and life path based on four pieces of information: the year, month, day, and hour of their birth. Each pillar is represented by two characters from a traditional 60-cycle calendar, giving you eight characters total (hence the alternate name saju paljja, 사주팔자, meaning “four pillars, eight characters”).
If Western astrology gives you one of twelve zodiac signs based on your birth month, saju goes several layers deeper. The day pillar (일주, ilju) in particular is considered the most direct representation of your core self — your instincts, your energy, the way you move through the world.
There are 60 possible day pillars. Each one carries its own symbolic image, tendencies, and energy profile. And as you’re about to see, TXT’s five day pillars make for a surprisingly compelling read.
One important note: a complete saju analysis requires the hour of birth (the fourth pillar), which hasn’t been publicly confirmed for any of the members. Everything here is based on the day pillar and publicly available birth dates, and is intended as a fun cultural lens — not a definitive forecast.
Soobin (December 5, 2000) — Jeong-yu (丁酉), The Lucky Blue Pig
Soobin’s day pillar is Jeong-yu (丁酉) — the image of a small, steady flame burning bright atop polished metal. In saju, this is an exceptionally fortunate pillar. The expert’s description? “A top-tier lucky blue pig — the kind of pig that was simply born blessed.”
The Jeong-yu pillar is one of only four day pillars that carry the Cheonul Gwiin (天乙貴人), the highest-ranked auspicious spirit in Korean astrology. Add in the Munchang Gwiin (文昌貴人) and Hakdang Gwiin (學堂貴人) — spirits associated with intelligence and wisdom — and you have someone who was genuinely born with good fortune surrounding them.
In terms of personality, Soobin’s energy surges when he feels recognized and respected. He has a strong instinct to protect his reputation and the people around him, and his saju strikes an unusually balanced harmony between yin and yang energies — which translates into a natural ability to hold the center of a group and keep things running smoothly.
From a face-reading (관상, gwansang) perspective: his naturally upturned lip corners suggest a person built to receive good fortune, though his upper lip being thinner than the lower can mean his drive occasionally outpaces his stamina.
His lucky colors are blues, greens, sky blue, and pink. He’s advised to avoid black and white.
Most importantly, when looking at TXT as a whole — Soobin’s saju is structurally the one that needs to carry the team with warmth. Not just as the official leader, but as the emotional and energetic center. The chart says so.
Beomgyu (March 13, 2001) — Eul-hae (乙亥), A Flower in the Rocks
Beomgyu’s day pillar is Eul-hae (乙亥) — a delicate flower (eul, 乙, the gentle wood element) sitting above deep, cold water (hae, 亥). The expert’s image for this pillar is striking: “a flower desperately trying to take root in the cracks of a rock — no soil beneath it, just raw will and instinct keeping it alive.”
Of all five members, Beomgyu is the only one whose saju is composed entirely of yin (陰) energy. This makes him extraordinarily sensitive and attuned to others — the member who notices things no one else does, who carries feelings quietly and deeply. But that same structure means there’s a lot being held in. Beneath the playful exterior, there’s suppressed intensity, a quiet rebelliousness, and a drive for change that doesn’t always show on the surface.
He’s also the member most naturally inclined to support Soobin, according to the saju reading — their energy structures complement each other in a way that makes their bond almost written in the chart.
From a face-reading standpoint: warm, expressive eyes that signal deep emotional generosity — though perhaps a touch too generous when it comes to keeping track of what’s his.
For stress relief, nature is key. Mountains, the ocean — spaces where the noise stops.
In terms of timing, Beomgyu’s saju follows a slow-burn trajectory, with his fortune building most strongly from around age 32 onward. He’s already impressive — but the best is genuinely still ahead.
Yeonjun (September 13, 1999) — Mu-jin (戊辰), The Golden Dragon
Yeonjun’s day pillar is Mu-jin (戊辰) — a vast, fertile earth beneath a coiled dragon. The expert called it simply: “the golden dragon.”
The Mu-jin pillar is known for its scale. People born under it tend to have a presence that draws others in naturally — warm and easy to be around on the surface, but with a fierce inner core of pride and ambition that doesn’t bend easily. Yeonjun fits this to a startling degree: approachable and generous with the team, but unmistakably the person in the room with the strongest gravitational pull.
He’s a perfectionist. He wants things clear, defined, done right. His self-expression is powerful and he has a competitive streak that pushes him to carve out his own style rather than follow anyone else’s. That same energy means he can clash with members who have similarly strong force — but it also means he brings one of the most defined artistic identities in the group.
The Mu-jin pillar also carries the Baekhosaul (白虎殺) — a marker associated with fierce fighting spirit, strong responsibility, and the ability to push through adversity without breaking. TXT’s eldest with the steady spine: it tracks.
Taehyun (February 5, 2002) — Gap-jin (甲辰), The Blue Dragon
Taehyun’s day pillar is Gap-jin (甲辰) — a great tree with deep roots in rich soil, or in the saju expert’s words: “the blue dragon, the unbending tree.”
His saju carries exceptionally strong yang (陽) energy — active, driven, and dominant. He’s the kind of person who, once he decides something, cannot be talked out of it. The expert’s analogy is memorable: like a pine tree in a storm — the roots might tear from the ground before the trunk agrees to bend. That’s Taehyun. Strong convictions, deep creativity, and a standards bar he sets for himself that few would voluntarily sign up for.
From the outside, this reads as the “mature maknae” energy fans have always clocked — the youngest member who somehow feels like the most self-possessed person in the room. His no-nonsense directness isn’t coldness; it’s precision.
Taehyun’s most powerful period comes in his late 30s, when the chart opens up significantly. The discipline and seriousness he brings to everything now is laying groundwork for something larger down the road.
Huening Kai (August 14, 2002) — Gap-in (甲寅), The Blue Tiger
Huening Kai’s day pillar is Gap-in (甲寅) — both the heavenly stem and the earthly branch are pure wood energy (甲木 and 寅木). This is one of the most concentrated, powerful day pillars in the 60-cycle system. The expert’s name for it: “the blue tiger” — and also “the unbending great tree,” an image he shares with Taehyun.
The keywords for Gap-in are strength, self-respect, and conviction. Huening Kai’s warmth and easygoing exterior can be deceiving — underneath it is someone with extremely clear internal standards and a deep need to feel in control of his own space and direction. He’s not aggressive about it, but he knows what he wants, and he holds to it quietly and firmly.
His saju also carries strong yeokmasal (驛馬殺) — the “traveling horse” energy associated with wide activity ranges and overseas fortune. For someone with dual Korean-American heritage who has spent his career performing globally, this is hard to overlook.
Like Taehyun, the strong yang energy means high confidence and persistence — but it also means he needs space to operate on his own terms to function at his best.
The Next 3 Years: TXT’s Golden Window
Reading each member individually is compelling enough. But the most striking finding from the full team reading is this:
From this year forward, all five members’ fortune cycles are rising at the same time — a window of roughly two and a half to three years.
This kind of alignment across an entire group is genuinely rare. According to the saju analysis, if TXT uses this period to communicate openly, pour energy into their work, and push forward together, the team will stabilize and elevate in a way that becomes a defining chapter in their career.
Individual timelines vary — Beomgyu builds from 32, Taehyun’s peak hits in his late 30s — but the collective upswing is now. The chart suggests this is the moment to go all in.
Five Pillars, One Team
Here’s the picture when you step back and see it whole:
The golden dragon Yeonjun anchors the team’s direction and spirit. The lucky blue pig Soobin holds the center with warmth and keeps everything running. The rock flower Beomgyu adds emotional depth and the sensitivity that connects. The blue dragon Taehyun drives with sharp ambition and unshakeable standards. The blue tiger Huening Kai fills the space with broad, vital energy that moves freely across any terrain.
Strong individuals, distinct energies — and yet the analysis confirms what fans have felt for years: the connective threads between them are real. Soobin’s chart is built for warmth toward this specific team. Beomgyu’s natural instinct pulls toward Soobin. The strong yang energies of Taehyun and Huening Kai mirror each other in a way that creates friction and momentum at once.
Saju doesn’t tell you what will happen. But it does offer a different language for understanding why certain people, when they come together, feel like more than the sum of their parts.
TXT might just be one of those cases.
